Description
Stop checking competitor prices manually.
This workflow monitors product prices across multiple online retailers every day — automatically. The moment a price changes, you get an instant Telegram alert with the product name, old price, new price, and a direct link to the page.
Set it up once. Let it run forever.
What it does
Scrapes product pages daily using ZenRows with JS rendering and residential proxies
Extracts prices via JSON-LD structured data — works across most major retailers
Compares each price against the last known value stored in an n8n DataTable
Tracks full price history for every product over time
Sends an AI-written summary alert via Telegram only when prices actually change
Updates all records automatically — no manual database management
What's inside
Ready-to-import n8n workflow (14 nodes, fully documented with sticky notes)
Full setup guide — step by step from zero to running in ~15 minutes
DataTable schema template for instant import
Sample Amazon product URLs to test immediately after setup
What you need
n8n (self-hosted or cloud)
ZenRows API key (web scraping)
OpenAI API key (alert generation)
Telegram Bot token
Who it's for
Perfect for e-commerce store owners, small businesses, and anyone who needs to stay on top of competitor pricing without lifting a finger.
P.S. I actually use this workflow myself to monitor the price of a tablet I want to buy. I simply pasted the product URLs from a few local retailers and now every morning,if any price changed overnight, I get a Telegram message. That's it. No app, no subscription(only Open Ai, zenrows have free tier), no manual checking.
